This study is based on the reproductive and
growth biology of the specie Sander Lucioperca that
is a freshwater fish, more responsive in the world and
major in aquaculture. A total of 362 specimens of S.
lucioperca were collected from the Bouhamdane
dam in Guelma, by monthly sampling from november 2019 to october 2020. The sexes of specimens
were determined macroscopically and the observed
sex ratio was in favor of males during the whole cycle of study. This study was carried out to determine
the gonado-somatic index (GSI), the liver somatic
index (LSI) and the condition factor (K) show variations related to the reproductive cycle. For the study
of age, 3 groups were identified for females and
males. Size frequency distributions and growth parameters were analyzed using the ELEFAN1 method,
using FISAT II software. According to Von Bertalanffy parameters, male pikeperch shows faster
growth (L∞=48.30cm, K=0.66 year-1, Ф=3.18) than
females (L∞=46.20cm, K=0.57year-1, Ф=3.08),
which is rare in teleost fish. Weight growth varies
between the two sexes, it is minorant in males and
the combined sex (b<3) and isometric (b=3) in females.
